One of the most controversial figures in nineteenth-century American history, Thaddeus Stevens is best remembered for his role as congressional leader of the radical Republicans and as a chief architect of Reconstruction. Long painted by historians as a vindictive 'dictator of Congress,' out to punish the South at the behest of big business and his own ego, Stevens receives a more balanced treatment in Hans L. Trefousse's biography, which portrays him as an impassioned orator and a leader in the struggle against slavery.
